A reusable sensor based on a phosphonate-substituted Ru( ii ) complex allows for selective detection as low 10 −13 M of Cu 2+ ions in aqueous solutions.

campylobacter jejuni is a major cause of food-borne diarrhea in many countries. poultry and poultry products are known as important sources of human campylobacteriosis. in this study, conventional culture and multiplex pcr methods were compared for the detection of c. jejuni isolated from poultry carcasses. a total of 100 samples, representing 20 broiler flocks, were collected from poultry carc...

A procedure for measuring in situ sulfide concentrations by coupling diffusive gradients in thin films (DGT) to solid-state ion-selective electrodes (ISE) is described and evaluated. Laboratory tests were performed to evaluate the coupling of these techniques, and these results were compared to the previously used methods of computer imaging densitometry (CID) and methylene blue. An average elu...

Wavelength-selective uncooled infrared (IR) sensors are highly promising for a wide range of applications, such as fire detection, gas analysis and biomedical analysis. We have recently developed wavelength-selective uncooled IR sensors using square lattice two-dimensional plasmonic absorbers (2-D PLAs). The PLAs consist of a periodic 2-D lattice of Au-based dimples, which allow photons to be m...

Odour detection thresholds, that we have previously obtained, have been analysed by a general equation for selective transport. It is shown that such selective transport can account for some 77% of the total effect. The remainder is due to a specific size effect, that might involve odour-binding proteins, and a specific effect for aldehydes and carboxylic acids. Our analysis raises the question...

Detection of volatile organic compounds (VOCs) using non-selective sensor requires an array of multiplexed sensors followed by pattern recognition approach. Based on this concept, we compare three different approaches for selective detection of ethanol, ammonia, toluene, acetone and chloroform at different concentrations using non-selective sensors which are: (a) an array of sensors operated at...

| This paper describes a new error resilient analysis{by{synthesis coding scheme and its application for robust still image transmission over DS-CDMA Rayleigh fading channels. The channel uses Reed-Solo-mon (RS) outer codes concatenated with Convolutional inner codes, and truncated type-I hybrid ARQ protocol based on the selective repeat strategy and the RS error detection capability.
